Dear Dmitriy, Yes that is the correct projection code, but the problem is - and hence my original question - that the “Times” projection referred to on the link you sent me is not defined in proj4. I’m wondering if anyone has programmed it, or if someone would be so kind as to assist me in making my own code for a new map projection for proj4.
